Flexible interfaces support a wider variety of
application needs—SerDes, fiber for long distances or
additional 10/100/1000TX ports.
Provides the most cost effective Gigabit conectivity to
the desktop for all remote, branch, and home office
needs.
802.1Q tag VLAN, trunking, and 802.1p priority
enables the switch to be designed into a wide variety of
applications from unmanaged to smart switch.
CPUs are not required to initialize and run in costsensitive unmanaged applications, providing true Plug
and Play connectivity.
Internal oscillator circuit simplifies design and reduces
overall system cost.
Ability to gather and support basic management
statistics with only a very low cost microcontroller.
Low-cost management using the on-chip MIB registers
allows the collection and transmission of statistics for
each port and allows an upward migration path for
corporate users.
On-chip HP auto-MDI/MDIX on all tranceivers
automatically detects and corrects for crossover cables
and allows direct switch-to-switch connection.

The Broadcom BCM5382M device is a highly integrated
solution. It combines all the functions of a high-speed switch
system, including packet buffer, PHY transceivers, media access
controllers, address management, and a nonblocking switch
fabric into a single 0.13 µm CMOS device. It complies with
IEEE 802.3, 802.3u, 802.3ab 802.3x specifications, including the
MAC control, pause frame, and auto-negotiation subsections,
providing compatibility with all industry-standard Ethernet, Fast
Ethernet, and Gigabit Ethernet devices.
This device contains eight full-duplex 10BASE-T/100BASE-TX
Fast Ethernet transceivers and one 10/100/1000BASE-T
transceiver, each of which performs all of the physical layer
interface functions for 10BASE-T Ethernet on Category 3, 4, or
5 unshielded twisted-pair (UTP) cable and 100BASE-TX Fast
Ethernet on Category 5 UTP cable.
SPI or EEPROM interfaces provide easy programming of the
802.1p QoS. This allows switch traffic to be given different
classes of priority or service—for example, voice traffic for IP
phone applications, video traffic for multimedia applications, or
data traffic for e-mail applications. Up to 4,000 VLANs can be
set up via the SPI port.
Even though this device is primarily targeted for the costsensitive unmanaged market, very low cost management can

also be provided using the proprietary MIB Autocast™
function. MIB Autocast encapsulates the on-chip MIB
statistics and sends them out automatically on a predefined
port (or ports) at programmed intervals. This feature is part of
the 8051 micro smart switch option for basic "smart
management" via a console port.
As part of the "smart switch" mode, the BCM5382M
periodically transmits Ethernet frames on a designated port. The
frames can be intercepted by an external management probe or a
dedicated network management application, resident on any
node within the network. In addition, the ROBOSmartswitchTM
software provides system and port configuration, VLAN and
QoS set up, and IGMP snooping.
The BCM5382M designed to work in unmanaged stand-alone or
managed mode via the on-chip MII interface to an ARM7 CPU.
This provides support for the Ethernet-like MIB, bridge MIB,
layer 2 management functions, private MIB, MIB II and 4 groups
of RMON. ROBO-managed LinuxTM software also supports
RTOS, BSP and loader, SNMP agent, console, WEB UI,
spanning tree, Tenet UI, port mirroring, trunking and easy
programming of VLAN groups, QoS priorities and IGMP
snooping.
